TECHNICAL FIELD

The present invention relates, in general, to methods for manufacturing cake decorating accessories and the decorating accessories and, more particularly, to a method for manufacturing a cake decorating accessory and the decorating accessory, which is used in producing a more dramatic and attractive atmosphere in places where various celebratory events, such as birthdays or anniversaries, are held, through a congratulatory message or picture being displayed by heat transferred from a heating unit.

BACKGROUND ART

Generally, a cake is a kind of dessert made by baking dough in which butterfat, eggs, sugar, milk and spices, etc. are mixed with wheat flour which is the main ingredient of the cake. According to the dough and cooking method, cakes are classified into a sponge cake, a butter cake, a pâte à choux dough cake, a yeast dough cake and a cookie dough cake.

After a cake is made by baking the dough, the cake is decorated with a coated and squeezed icing. Coated icing means that various coating materials are spread on or cover the cake. Squeezed icing means that a cook decorates the cake with a desired line or shape using squeezing bags containing various squeezing materials.

The above-mentioned coated and squeezed icing is made of chocolate, creams, a meringue which is made by whipping the white of an egg mixed with sugar, and a marzipan which is dough made by mixing almond powder with syrup. Particularly, in the creams for the coated and squeezed icing, there are a whipping cream made by whipping a fresh cream including sugar, a butter cream in which an egg and sugar are included in butter, a ganache made by mixing chocolate with a fresh cream, and a grass royal which is used for a wedding cake decoration and is made by mixing sugar, the white of egg, lemon juice and tartaric acid.

Furthermore, accessories, such as a sugar flower, nuts, and a harmless sign plate which is made by printing desired figures and letters on rice paper made of rice using an edible ink, are placed on the cake decorated with the coated and squeezed icing, thus completing the cake decoration.

In addition, various sugar dolls or candles may be fastened to the cake for decoration and to express a special congratulatory message.

For example, a wedding doll or candles to show the age of a person celebrating a birthday are fastened to the cake, so that the atmosphere of the celebratory event, such as a birthday or anniversary, is joyful.

Typically, upon buying a cake, candles, knives, firecrackers, and cards are provided along with the cake. The above-mentioned accessories are useful to create a festive and joyful atmosphere at the celebratory event, such as a birthday or anniversary.

However, limitations are imposed on producing such an atmosphere using conventional cake accessories. Candles, which are provided with the cake, have simple shapes and functions. Accordingly, it is difficult to produce more beautiful and varied atmospheres by candlelight resulting from several candles. Thus, a new decorating means has been desired to solve the above-mentioned problems.

In an effort to overcome the above-mentioned problems experienced with conventional cake accessories, a cake decorating accessory for the climax of the celebratory event was proposed in Korean Patent Laid-open Publication No. 2004-0040637, which was filed by the inventor of the present invention, entitled ‘CAKE DECORATING ACCESSORY’.

In the conventional cake decorating accessory disclosed in No. 2004-0040637, a congratulatory message screening on a transfer paper is displayed by heat transferred from a heating unit. The conventional cake decorating accessory includes a base which has the heating unit and a display unit provided on the base.

The base further has a support pin at a lower surface thereof, so that the base is easily and stably attached to the cake. The heating unit and the display unit are provided on the base opposite each other.

The display unit includes transfer paper with thermo-chromatic microcapsules. The display unit displays a congratulatory message on the transfer paper while responding to the heat transferred from the heating unit. The heating unit has a plurality of candles. Candlelight provided by the candles functions to transfer heat to the display unit, and as well, to produce a graceful and mysterious atmosphere. Thus, the atmosphere of the celebratory events, such as birthdays or anniversaries, is beautifully created.

In the meantime, another conventional cake decorating accessory was proposed in Korean Patent Application No. 2003-17031, which was filed by the inventor of the present invention, entitled ‘CAKE DECORATING ACCESSORY WITH MESSAGE DISPLAY FUNCTION’.

This conventional cake decorating accessory includes a decorating plate which has a support pin at a lower surface of the decorating plate, thus being fastened to a cake. The cake decorating accessory further includes a heating unit and a message board which are provided on the decorating plate opposite each other. A thermo-chromatic transfer paper is attached to the message board.

In the conventional cake decorating accessories, birthday or anniversary congratulatory messages are printed on the transfer papers, before thermo-chromatic microcapsules are layered on the transfer papers. By heat transferred from the heating unit to the display unit, outer layers of the transfer papers become colorless. Therefore, the printed congratulatory messages are exposed to the outside. Thus, the atmosphere of the celebratory events, such as birthdays or anniversaries, reaches the climax.

However, in the cake decorating accessory disclosed in No. 2004-0040637 and the cake decorating accessory with the message display function disclosed in No. 2003-17031, users cannot directly write the congratulatory messages that become exposed to the outside when the outer layers of the transfer papers become colorless. Therefore, the users cannot express individual congratulatory messages. Thus, the conventional cake decorating accessories cannot accommodate the recent trend of customizing the congratulatory message. To solve the above-mentioned problems, a new cake decorating accessory is required.

DISCLOSURE Technical Problem

Accordingly, the present invention has been made keeping in mind the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a cake decorating accessory, in which a congratulatory message printed on transfer paper is gradually displayed by heat transferred from the heating unit, whereby the atmosphere of places where various celebratory events are held reaches the climax, and which is capable of producing more pleasant and various atmospheres through a variously shaped base and candlelight from a plurality of candles.

Another object of the present invention is to provide a cake decorating accessory which allows a user to directly write a congratulatory message on transfer paper, so that the congratulatory message is displayed when an outer layer of the transfer paper becomes colorless, thus expressing the individual congratulatory message, thereby accommodating the recent trend of customizing the congratulatory message.

FIG. 10 is a perspective view showing the construction of a cake decorating accessory, according to a third embodiment of the present invention. FIG. 11 is a side view of the cake decorating accessory of FIG. 10. As shown in FIGS. 10 and 11, the cake decorating accessory according to the third embodiment includes a base 30 having a surface area wider than those of the first and second embodiments. A message board 40 is mounted at a central position on the base 30. Both a base paper 77 and a thermo-chromatic film 80, which are manufactured through the above-mentioned cake decorating accessory manufacturing method, are attached to each surface of the message board 40.

FIG. 12 is a perspective view showing the construction and an operation of a cake decorating accessory, according to a fourth embodiment of the present invention. As shown in FIG. 12, the cake decorating accessory according to the fourth embodiment includes both a message board 40 with a base paper 77 and a thermo-chromatic film 80 which are manufactured through the above-mentioned cake decorating accessory manufacturing method. The message board 40 has a support pin at a lower end thereof. The message board 40 is directly attached to cake. Thereafter, a plurality of candles 11 is put on the cake around the message board 40 having the base paper 77 and the thermo-chromatic film 80. Thus, heat generated from the burning candles 11 changes the thermo-chromatic film 80 into a transparent film.

The operation and effect of the cake decorating accessory of the present invention having the above-mentioned construction will be described herein below.

For the birthday or anniversary ceremonies, a plurality of candles is pinned on a cake 10. At this time, the cake decorating accessory of the present invention is mounted on the cake along with the plurality of candles as shown in FIGS. 5, 9, 10 and 12.

That is, the cake decorating accessory of the present invention is attached to the cake 10 by use of the support pin 31 provided under the lower surface of the base 30. Thereafter, the candles 65, or the candles 11 which are directly attached to the cake 10 are burned. While the candles 65 or 11 are burning, heat is transferred from the candles 65 or 11 to the message board 40 with the thermo-chromatic film 80. Then, the thermo-chromatic film 80 becomes transparent. As a result, congratulatory messages, which were covered by the thermo-chromatic film 80, are exposed to the outside.

The thermo-chromatic film 80 is made by mixing an oil-based ink with thermo-chromatic microcapsules having thermo-chromatic dyes and applying the mixed material to the transparent synthetic resin film 84. The thermo-chromatic dyes included in the thermo-chromatic microcapsules each have a property in which, when the thermo-chromatic microcapsule is heated higher than a referential temperature, a color of the thermo-chromatic dye is changed into a different color, colorlessness or a border color, and, when the thermosensitive microcapsule is cooled lower than the referential temperature, the changed color of the thermo-chromatic dye is restored to the original color. By the above-mentioned property of the thermo-chromatic dye, when the thermo-chromatic film 80 is heated to a temperature higher than a predetermined temperature, the thermo-chromatic film 80 becomes colorless.

Then, the congratulatory message of the base paper 77, which had been covered by the thermo-chromatic film 80, is externally displayed, whereby the atmosphere of the celebratory event reaches the climax. Particularly, a guest of honor at the celebratory event may be impressed by the congratulatory message which is gradually displayed through the heat transfer process.

Furthermore, the congratulatory message is displayed in a joyful atmosphere in which a festive song is sung, or a celebratory message is read. Therefore, the atmosphere of the celebratory event reaches the climax. Thus, more impressive celebratory events can be created. In addition, all the persons participating in the celebratory event, including the guest of honor, are interested in such a gradually displayed message and thus can concentrate on the celebratory event.
